WHAT IS TPMS AND TYPES OF TPMS

WHAT IS TPMS?

TPMS is an abbreviation of Tyre Pressure Monitoring Systems, which are electronic systems which monitor tyre pressure and temperature, they inform drivers of low pressure or sudden deflation of tyres.
These systems transmit data to the vehicles ECU and is depicted via a pictogram display, voice activation or a simple warning light within the vehicle.
There are 2 main types of TPMS systems. Indirect and direct systems.

Indirect TPMS System

The vehicle’s ECU/ESC uses the ABS sensors to calculate the rate at which each wheel rotates, therefore determining if a tyre has a reduction in pressure in relation to the others wheels.

Direct Fit System

Consists of a TPMS sensor installed directly on to the valve of each wheel. The sensors use radio frequencies to transmit the data to the ECU.
These sensors send information relating to the tyres pressure and temperature in near real time through to the vehicles ECU via RF signals.

Reasons to replace TPMS sensors

Common reasons for replacing the vehicles TPMS sensors include:

  • Tyre changing has physically broken the sensor
  • TPMS Battery depleted
  • Stem damaged or corroded (Stems can be provided separately)
  • Incorrect or not performing the TPMS relearn procedure

Mobiletron offer a range of sensors in universal (programmable) or direct fit (pre-programmed). To view our full range of TPMS sensors please click here
